Barber - Model DR 12/26 -Dual Rotary Drill (Truck Mounted)

This drill is equipped with a 900 cfm/350 psi compressor, giving the machine depth rates of 1800 feet rotary and 800 feet of 8` diameter steel casing. The basic concept of the dual rotary rig allows a lower rotary drive unit to advance casing up to 24` through unconsolidated overburden. This rig can successfully operate in locations where casing hammers and reamers have been unsuccessful. This unit`s versatility makes it one of the most efficient and cost effective methods for drilling holes in difficult formations.
